(Cl. 137-595 The present application is acontinuation-in-part of my co-pending application No. 404,099; filedJanuary 14, 1954, now Patent No. 2,856,959.

Said co-pending application No. 404,099 is, in its turn, acontinuation-in-part of my copending application No. 150,583; filedMarch 20, 1950, now abandoned.

The present invention is directed to a connecting device for use withfluids and more particularly to a connecting device having a socketportion and a plug portion, the socket portion being adapted to besecured to a part of a building or other structure having. a circulatingfluid system, the plug portion being adapted to be connected to anappliance or other device for utilizing the circulating fluid. g

In accordance with the present invention, the plug portion and socketportion are formed with co-acting members which. inter-engage when theplug portion is inserted within the said socket. When the plug isinserted within the socket and the plug is rotated relative to thesocket the co-acting members inter-engage and advance the plug withinthe socket to provide a fluid'tight connection between the conduit.orconduits of the plug por tion and the corresponding conduit orconduits in the socket portion.

According to the preferred construction the present invention isdirected to a valve coupling. comprising a socket portion, includingavalve casing having a side wall, at least one fluid supply, conduitcommunicating with the valve casing, the side .wall forming aplug-receiving cavity, and a closure memberv rotatably mounted in saidcavity between open and closedpositions, said closure member having atleast one. connectingconduit therethrough, said connecting conduithaving a firstand a second end, said firstend communicating-with saidsupply conduit only when said closure memberis in the open position; anda removable plug portion insertable in said. second end, said plugportion including at leastv one conduit for communicating with saidsecond end of said. connecting conduit. in said closure member, saidside wall and said plugportion being formed with coacting members whichinter-engage to advance said plug portion within said second end uponinsertion of said plug into said second end andupon relative rotationbetween said plug portion and said socket portion to. provide a fluidtype connection between said conduit in said plug portion and saidsecond .end of said connecting" conduit and means on said plug portionto inter-engage said; clo- By providing co-acting members having such aconstruc- 7 "tion the fluid pressure-in the conduits cannot serve-toPatentedMara 15, 1960 ice socket. In other words, the fluid pressuredoes not produce a force component sufficiently strong to overcome thefriction maintaining the plug in the socket.

According to;th e invention the plug and socket may comprise one or morefluid conduits depending upon the use to which thejconnection is to beput. This connection may be used with any type of fluid such as water,steam or gas.

One of the objects of the present invention is to provide a valvecoupling or connecting device for fluids, said device consisting of aplug portion and a socket portion so constructed that the fluid pressurecannot force the plug out of the socket.

It is a further object to provide a valve connection having a plugportion and a socket portion, one of said portions being connectable toa building or other source of fluid while the other portion isconnectable to a portable appliance. t

It is a further object of the present invention to provide a connectingdevice or valve coupling having a plug portion and asocket portionwherein the plug portion is insertable within the socket portionutilizing only one hand.

These and other. objects will-become readily apparent from the followingdetailed description 'ofpreferredembodiments of the present invention asillustrated in the annexed drawings wherein:

Within the cavity 24 a rotating closuremember 4 is mounted, which has a coaxial pipe portion 26 integral withjet rigidly secured to the same, extending through an'opening in thebottom of said cavity, and projecting out bf the back portion of thesocket core at its furthest end.

'Figure 8 shows a simplified arrangement for a lavatory 56 provided withthe means 57 for rendering the same movable. Said arrangement comprisesone duct 58 for supplying a liquid 'to a tap and a separate duct 59connected to' the check valve of the lavatory. The ducts 58 and 59 areconnected to the plug 60, which is insertable in the socket 61.

When referring exclusively to liquids, gas or steam, throughout thepresent application, it only means that said reference only deals with amere example or an application preferable in connection with such typeof fluid or condition of same, but it must be understood that saidexample or application may be used in connection with any other type orcondition of the fluid, provided the design of the device allows to doso, or adding the variations or simplifications resultant of the Theterm building installation and derivative or similar expressions involveevery installation or adherence respective of a wall, whether it belongsto a building or not, being possible that it belongs to a ship, a train,an aircraft, etc. Also, any reference to appliances for the use offluids involves apparatus designed for the same use, and vice versa. Inthe same manner, the words supplying and others derivating thereof havethe same meaning as feeding and derivative words. Also, the expressionconnecting organ has the same meaning as the word interconnector.

When, due to low fluid pressure, there is no fear that the plug will bedriven out, it is not necessary to make special provision to prevent thefluid pressure from forcing the plug out of the socket. Of course, thisdoes not mean that there can be eliminated simple means to keep the plugin the socket since it is necessary to avoid accidental uncoupling ofthe plug by means of the operator of the appliance. Furthermore, whenthe fluid supplied to the appliance must be clean, it will be necessaryto include provision for the free flow of fluid by the action of gravityto prevent used water from flowing back toward the parts of theappliance which must be kept in a good condition of cleanliness.
